The frequency is slowly increased. once it passes the critical value fb, the student hears the ball bounce. there is now enough information to calculate g. what is g? express the magnitude of the acceleration due to gravity in terms of fb and a. view available hint(s)

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
